Chilean occupation of Potosi

The Chilean occupation of Potosi (4-7 February 1890) occurred in early 1890 when the 30,000-strong Chilean army invaded the Argentine-held Potosi region in what is now southern Bolivia. The government of Chile, led by the nominally anti-war Socialist Party of Chile, declared that the Argentine occupation of southern Bolivia was unfair and that the Chilean army was moving into the Potosi region to occupy the southern parts of the country in the aftermath of the War of the Pacific. The Chilean military invaded the region without resistance, marching into Potosi and occupying Oruro and the regional center of Potosi. The occupation was one of Chile's many military conquests during the late 19th century.
